An exploration of the organisational stressors encountered by international disability footballers

Presently, disability athletes remain under-represented in organisational stressor research. Our study sought to bring novel insights to this area by determining the organisational stressors experienced by international disability footballers. Twelve current international disability footballers (10 male, 2 female) from a range of UK impairment squads took part in the study. Semi-structured interviews were completed with each participant, and data were analysed by content analysis procedures. Organisational stressors data were abstracted into Arnold, Wagstaff, Steadman, and Pratt’s (2017) concepts, and Arnold and Fletcher’s (2012) four general dimensions: leadership and personnel issues, cultural and team issues, logistical and environmental issues, and performance and personal issues, revealing a series of football specific nuances. Our study is the first exploration of the prevalence of organisational stressors within international disability football. Our study also provides practitioners with an understanding of the common and unique organisational stressors faced by international disability footballers. Finally, we suggest a series of practical recommendations for policy development within disability football organisations to aid athletes to effective manage organisational stressors.</div

A binuclear vanadium oxyfluoride: di-μ-oxido-bis­[fluoridooxido(1,10-phenanthro­line)vanadium(V)]

The title compound, [V2F2O4(C12H8N2)2], is a centrosymmetric binuclear vanadium(V) species with the metal ions in a distorted octa­hedral environment. The symmetry-equivalent VV atoms exhibit coordination geometries defined by cis-terminal fluoride and oxide groups, unsymmetrically bridging oxide groups and the N-atom donors of the phenanthroline ligands. The crystal packing is stabilized by weak inter­molecular C—H⋯O and C—H⋯F hydrogen bonds

Chronic idiopathic urinary retention:Comorbidity and outcome in 102 individuals

OBJECTIVES: Chronic Idiopathic urinary retention is poorly understood. One small study suggests higher than expected rates of functional neurological disorder and pain comorbidity which may have implications for understanding the disorder. We investigated the frequency of functional neurological disorder, chronic pain other medical and psychiatric comorbidity, triggers of urinary retention, results of urodynamic assessment, medication history, management, and outcome in patients with chronic idiopathic urinary retention.METHODS: A consecutive retrospective electronic notes analysis was undertaken of patients with chronic idiopathic urinary retention presenting to a secondary care urology clinic between Jan 2018-Jan 2021, with follow-up to their most recent urological appointment.RESULTS: 102 patients were identified (mean age of 41.9 years, 98% female). 25% had functional neurological disorder (n = 26), most commonly limb weakness (n = 19, 19%) and functional seizures (n = 16, 16%). Chronic pain (n = 58, 57%) was a common comorbidity. Surgical and medical riggers to urinary retention were found in almost half of patients (n = 49, 48%). 81% of patients underwent urodynamic assessment (n = 83). Most frequently no specific abnormality was reported (n = 30, 29%). Hypertonic urethral sphincter was the most identified urodynamic abnormality (n = 17, 17%). We noted high levels of opioid (n = 50, 49%) and benzodiazepine (n = 27, 26%) use. Urinary retention resolved in only a small number of patients (n = 6, 6%, median follow up 54 months), in three cases spontaneously.CONCLUSION: This preliminary data suggests idiopathic urinary retention is commonly comorbid with functional neurological disorder, and chronic pain, suggesting shared mechanisms.</p

Predicting tree distributions in an East African biodiversity hotspot : model selection, data bias and envelope uncertainty

The Eastern Arc Mountains (EAMs) of Tanzania and Kenya support some of the most ancient tropical rainforest on Earth. The forests are a global priority for biodiversity conservation and provide vital resources to the Tanzanian population. Here, we make a first attempt to predict the spatial distribution of 40 EAM tree species, using generalised additive models, plot data and environmental predictor maps at sub 1 km resolution. The results of three modelling experiments are presented, investigating predictions obtained by (1) two different procedures for the stepwise selection of predictors, (2) down-weighting absence data, and (3) incorporating an autocovariate term to describe fine-scale spatial aggregation. In response to recent concerns regarding the extrapolation of model predictions beyond the restricted environmental range of training data, we also demonstrate a novel graphical tool for quantifying envelope uncertainty in restricted range niche-based models (envelope uncertainty maps). We find that even for species with very few documented occurrences useful estimates of distribution can be achieved. Initiating selection with a null model is found to be useful for explanatory purposes, while beginning with a full predictor set can over-fit the data. We show that a simple multimodel average of these two best-model predictions yields a superior compromise between generality and precision (parsimony). Down-weighting absences shifts the balance of errors in favour of higher sensitivity, reducing the number of serious mistakes (i.e., falsely predicted absences); however, response functions are more complex, exacerbating uncertainty in larger models. Spatial autocovariates help describe fine-scale patterns of occurrence and significantly improve explained deviance, though if important environmental constraints are omitted then model stability and explanatory power can be compromised. We conclude that the best modelling practice is contingent both on the intentions of the analyst (explanation or prediction) and on the quality of distribution data; generalised additive models have potential to provide valuable information for conservation in the EAMs, but methods must be carefully considered, particularly if occurrence data are scarce. Full results and details of all species models are supplied in an online Appendix. (C) 2008 Elsevier B.V. All rights reserved

Training future generations to deliver evidence-based conservation and ecosystem management

1. To be effective, the next generation of conservation practitioners and managers need to be critical thinkers with a deep understanding of how to make evidence-based decisions and of the value of evidence synthesis. 2. If, as educators, we do not make these priorities a core part of what we teach, we are failing to prepare our students to make an effective contribution to conservation practice. 3. To help overcome this problem we have created open access online teaching materials in multiple languages that are stored in Applied Ecology Resources. So far, 117 educators from 23 countries have acknowledged the importance of this and are already teaching or about to teach skills in appraising or using evidence in conservation decision-making. This includes 145 undergraduate, postgraduate or professional development courses. 4. We call for wider teaching of the tools and skills that facilitate evidence-based conservation and also suggest that providing online teaching materials in multiple languages could be beneficial for improving global understanding of other subject areas.Peer reviewe

A communal catalogue reveals Earth's multiscale microbial diversity

Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.Peer reviewe
